Steam SHiFT Codes 

Valve's Steam platform is the defacto king of PC Gaming launchers. It was one, if not the, first to market and maintains a strong position as the leader in PC Gaming estimated to have 75% marketshare in 2013. The SHiFT Codes below are designed for use in Steam titles. Even though Borderlands 3 is not supposed to be available until April 2020, many of the Universal codes can be redeemed in advance.
